To all whom t majz/ concern.'

Be it known that LCHERUBINO NANNINI,

a citizen of the United States, and a resident of Manhattan, county of Nye, and State of Nevada, haveinvented a new and useful Hair Clipper,A of which the following' is a specification.`

My invention relates in general to hair clippers as commonly used by barbers and has reference more particularly to means which may be considered in the nature of an attachment to enable the clippers to be used for cutting relatively long hair, whereas' heretofore the clippers have been only applicable to' clipping short hair.

As an example of the use of clippers equipped with the invention, it might be pointed out that as at present practiced clippers are usuallyused around the neck and discarded in vfavor-of shears when the hair on the side and ytop of the head is to be trimmed. Y W'ith m'yimproved means certain adjustments may be realized which will enable the clippers, as above stated, to be used for cutting the hair all over the head without the necessity of using shears. The attachment will enable the clippers to be used not only by barbers but also enable anyone to cut their own hair with every degree of satisfaction. Y V

The illustrative embodiment `of the invention is shown in the accompanying drawing, in which Figure 1 isa plan view of a conventional type of hair clipper `illustrating the application of my invention; Figure' 2 is a view in side elevation of the cutting head of the 'clipper showingjmy invention as applied thereto; Figure 3 is an enlarged view. in cross section on the line 3,-3 of Figure 2'; Figure 4c is a view in cross section on the line 4 4 of Figure 3, and Figure 5 is a bottom plan view lof a clipper head showing a part of my invention as applied thereto. i

Referring now to the drawing in detail, A represents a clipper having the customary fixed cutting blade, (5) and the slidably mounted `cutting blade (6). lt is of course known that the` ,blade (6) n is moved backend forth over the blade (5) by the handles of the clipperto produce .the re quired cutting effect between "the teeth of the cutters. According to "my invention propose. to mount a plate (7)V beneath the xedcutting blade (5) with the dimensions ofy the plate substantially corresponding vto` the dimensions ofthe blade (5). The plate is made with va plurality of teeth (8), theends of which being turned vupwardly as Y y.

best shown in Figuret. V A,"lfhe length ofthe teeth is longer than the lteeth of the blade (5). y To guide or 'direct' the hair to be clipped to the blades (-5) and (6), I `prefer to. hinge a guide strip (9) to the "plate- (7) at the commencement of thefteeth(8)` This guide strip is positioned transversely across the plate (7)v and the outer free edge of the same terminates in relatively short teeth (9,). Normallthe guide strip lies flush with the plate 7) butwhen theclippers are being used the` hair willpush the same up againstpthe under 'Iside of the blade (5), as best shown lin Figurefl.' The important feature of the invention resides in adjusting the kplates( `(7)"in` spaced relation relative to 'the blade (5) 'according to the desired cutting effect'to ybe accomplished. For instance,` to clip the hair long the plate (7) will be moved further away` from the blade (5)y than if the hair is to be clipped short.4 This elfect is obvious. f

To realize asuitable mounting, for the plate (7') aswell as to accomplish the vari-y ous adjustments of the sameas stated, I prefer to provide openings through the clipper including the crownl (11) with the openings and (13), the sameextending through these made to receiveV the upstanding posts` y(12)t i openings in the clipper and protruding a suitabledistance above'the same. VArranged on each face of the posts (12) and (13) is a rack (1.4). Riveted, brazed lor otherwise fixed upon the crown (ll) of the clipper-sis a housing (15), the samey having openings in its top through which the posts (12) and (13) are protruded.v Arranged transversely (16), the same having a bearing in opposite ends of the housing- (15) andcarrying pin-3A across the rack faces of the posts is ashaft ,t

has a turn'l-rnob or the like\"(19) lwhich enf ables the shaft (16) toberotated,'andvsince the pinions V(17) and (18) 4are flush with the racks (14), vthe rotation ofthe shaft ,(16) willmove the y.posits up anddown, which will in turn move the plate (7)` to "and *from spaced relation to the blade (5)' for realiz-I s i ing the adjustment r'previously lreferred to.' In order to hold the predetermined adjust-k lilo ico y ment of the plate (7) relatively of the blade y Ipropo'se to use' a key (20), thesaine j pin (22), which extends through an openby. throwing the key in in the top of the housing and enables the key to be slid to and from engagement with the racks (14).

By turning the thumb knob (19) the pinions `will move the posts and in turn the plate (7) to effect proper adjustment, and whenthe adjustment is made it may be held (20) in engagement with the racks (14). To hold the key inengagement with the racks it is suggested to use a' spring strip (23), see Figure l, so `that the, keyiis maintained Linder the influence of vthe spring and in engagement with the racks. v
